Re: Telnet Fails

Hi Christopher ,

Do you ensure telnet service works? I suggest you
1/Check telnet service ,is it enabled?
cat /etc/xinetd.d/telnet ,parameter disable should "= no"
2/Check xinetd service ,is it running?
/etc/init.d/xinetd status
3/Check firewall, is it allow port 21?
You should stop iptables to have a try. Perform command "/etc/init.d/iptables stop".
4/Check singularity from /var/log/messages
5/Check opened port ,perform "netstat -nl |grep 21" ,is it exist?

Re: Telnet Fails

telnet is not enabled in a standard linux install. This is because the password authentication travels across the network in clear text.

Yep, anybody on the network can sniff your password.

Consdier using ssh instead of telnet. It is enabled in all current Red Hat Installations.

To enable telnet

cd /etc/xinetd.d

Find the entry that says(is named) telnet

vi it.

change disable=yes to disable=no

save the file

service xinetd restart

Re: Telnet Fails

telnet is turned off by default in RH. Use the ssh protocol.

If must use telnet, ensure the package is loaded - do the rpm -qa | grep -i telnet

If loaded you will need to turn on within the xinetd.d and issue the command 'service xinetd restart'

Re: Telnet Fails

Christopher,

I want to second a recommendation made by SEP earlier -- consider using ssh instead of telnet. telnet is not a safe protocol -- password travels in plain text over the network.

Ross
